The Wacker Neuson is a genuine OEM Acorn Nut M16 designed for the PS2, PS3, and PS4 series submersible pumps. Sourced directly from Wacker Neuson, this fastener meets the exact material and dimensional specifications of the original hardware installed at the factory. It is confirmed to fit a wide range of PS-series models including the PS2-3703, PS3-3703, PS3-5503, PS4-3703, and PS4-5503, covering both 50 Hz and 60 Hz voltage configurations. When it comes to maintaining the structural integrity of your submersible pump, using the correct OEM hardware ensures a secure, leak-free assembly every time.
Key Features
- OEM-Grade Fastener Material — Manufactured to Wacker Neuson's original thread pitch and hardness spec for the M16 acorn profile, ensuring correct torque retention in wet and submerged environments.
- Drop-In Hardware Replacement — Threads directly onto existing M16 studs or bolts on PS-series pump housings with no modification to mating components.
- Broad PS-Series Compatibility — Fits PS2-3703, PS3-3703, PS3-5503, PS4-3703, and PS4-5503 submersible pumps across multiple voltage variants (220V, 400V, 440V, and 575V configurations).
- Enclosed Cap Design — The domed acorn profile shields the exposed thread end from corrosion and debris ingress, which is especially important in the wet and abrasive conditions these pumps operate in.
- Electrical Safety Consideration — On electric submersible pump assemblies, properly secured hardware is critical to maintaining housing integrity and protecting internal electrical components from water intrusion.
An acorn nut — also called a cap nut — is a domed fastener that threads onto a bolt or stud to secure an assembly while simultaneously covering and protecting the exposed thread end. On Wacker Neuson PS-series submersible pumps, these nuts play a structural role in holding pump housing components together under the pressure and vibration of continuous operation. When an acorn nut becomes corroded, stripped, or lost, it can compromise the clamping force of the assembly and leave exposed threads vulnerable to further damage, making timely replacement with the correct OEM part essential to keeping the pump sealed and operational.
